Question
A metallic ring is attached with the wall of a room. When the north pole of a magnet is brought near to it, the induced current in the ring will be
- First clockwise then anticlockwise
- In clockwise direction
- In anticlockwise direction
- First anticlockwise then clockwise
The correct answer is: In anticlockwise direction
As it is seen from the magnet side induced current will be anticlockwise.
